Specification of Letters Patent.

Patented Mar. 28, 1911.,

Application filed February 28, 1910. Serial No. 546,402.

To all whom it may concern:

Be it known that I, JAMES W. EAST, a citizen of the United States,residing at Raphine, in the county of Rockbridge and State of Virginia,have invented a new and useful Motor, of which the following is aspecification.

This invention has for its object the provision of a simple andeflicient motor for operating pumps, which will be found an effectivesubstitute for the ordinary windmill and which may be operated at anytime, irrespective of the condition of the wind. This object is attainedby the use of the mechanism illustrated in the accompanying drawings,and the invention consists in certain novel features of the same, aswill be hereinafter first fully described and then particularly pointedout in the claims.

In the drawings, Figure 1 is a side elevation of a mechanism embodyingmy invention. Fig. 2 is a similar view looking at the opposite side ofthe apparatus. Fig. 3 is an end elevation. Fig. 4 is a detailperspective view of the walking beam. Fig. 5 is a detail horizontalsection showing the guide for the vertical reciprocatory rack bar.

In carrying out my invention, I erect a pair of frames 1 which areconnected by suitable bracing bolts 2 in spaced relation adjacent themouth of a well. Between the side frames 1, I arrange a driving shaft 8which has its ends journaled in the said frames and carries a gear wheel4 on the side of which is pivoted a pawl 5 normally pressed by a spring6 into engagement with a ratchet disk 7 on the end of a drum 8, which issecured on the said driving shaft. A cable 9 is wound on the said drumand extends therefrom to a pulley or guide roller 10 at the outer end ofan arm 11 projecting from the main frame, and then extends up to andover a second pulley or guide roller 12 on the end of an arm 13 at theupper end of the frame, a weight 14 being attached to the end of thecable, as clearly shown in Fig. 1, whereby the dropping of the weightwill unwind the cable and thereby impart motion to the drum which will,in turn, be

transmitted through the ratchet disk 7 and pawl 5 engaging the same, tothe gear wheel 4 from which it will be transmitted to the mechanism tobe driven. The rotation of the gear wheel 4 is transmitted through atrain of gearing comprising spur wheels 15 and 16 and pinions 17 and 18to a crank shaft 19, mounted between the upper portion of the sideframes, the said crank shaft being provided with a pinion meshing withthe spur gear 16 and being connected by a link 20 with the lever arm 21of the segmental gear 22, which is pivotally mounted between the sideframes, as clearly shown. This segmental gear 22 meshes with a pinion 23on a rock-shaft 24 journaled in the side frames above the gear andprovided at one end with a crank arm 25, to the end of which is pivotedthe upper end of a connecting rod 26 having its lower end pivoted to oneend of a walking beam or lever 27 at the center of which is secured asegmental gear or rack 28, the center of the said rack being the pivotof the walking beam which pivot extends between one of the side frames 1and the supplemental frame 29 secured to the said side frame. Thissegmental gear or rack 28 meshes with a pinion 30 on a shaft 31journaled in the side frame 1 and the supplemental frame 29 and providedwith a pinion 32 on its end outside the supplemental frame, the saidpinion 32 meshing with a rack bar 33 disposed vertically in suitableguides 34 on the supplemental frame and connected to or forming a partof the pump rod by which water is drawn from the well and dischargedthrough the spout 35 into a trough 36.

On one end of the crank shaft 19 is a scape wheel 37 which is engaged bya pallet 38 mounted on the frame below the said wheel and adapted tooscillate so as to engage the said scape wheel and regulate the movementof the same and prevent a too-rapid descent of the operating weight 14.A stop arm 39 depends from the pallet 30 and oscillates freely as thesaid pallet operates. Upon the frame below the said depending stop armis a brake lever 40 which has one end projecting upward in the path ofthe said depending stop arm 39 and has its other arm flexibly connectedwith one end of an angle lever 41 fulcrumed upon the frame and havingits other end disposed over the tank and carrying a float 42 adapted toride on the water within the trough.

The construction and arrangement of the several parts of the devicebeing thus made known, it is thought the operation of the same will bereadily understood and appreciated. The main driving shaft is rotated bymeans of any ordinary crank handle so as to wind the cable 9 and,consequently, 'aise the weight to its highest position. Should thetrough 36 be filled with water, the float 4E2 will be at its highestpoint and the inner end of the lever 41 will, consequently, be depressedso as to hold the upper end of the brake lever 40 against the lower endof the, stop arm 39 and, therefore, prevent vibration of the pallet 38so that the scape wheel 37 cannot rotate and the mechanism will notoperate. As the water in the trough is used and the level of the samefalls, the float will descend and will thereby vibrate the lever ll sothat the inner end of the same will lift the lower end of the brakelever 40 and swing the upper end of the same away from the stop arm 39so that the pallet will be free to vibrate and, consequently, theseveral gear wheels may rotate under the influence of the weight 1 fapplied through the drum and the ratchet wheel on the end of the same tothe main gear wheel 1-. The rotation of this gear wheel will betransmitted through the train of gearing to the crank shaft 19, and thelink 20 will follow the movement of the said crank shaft so as tovibrate the lever arm 21 and the segmental gear 22 carried thereby. Thevibration of the segmental gear 22 will be imparted directly to thepinion 23 and the rock shaft 24: will be oscillated, so that the crankarm 25 thereon will be given an up and down movement. This movement ofthe crank arm 25 will be transmitted through the connecting rod 26 tothe walking beam 27, so that the curved rack 28 thereon will be causedto act on the pinion 30 and vibrate the shaft 31 so that the pinion 32on said shaft will reciprocate the rack bar 33 and, consequently,operate the pump. As the trough fills, the float will rise and,therefore, actuate the brake lever 40 so as to throw the free end of thesame against the end of the stop arm 39 and again arrest the movement ofthe pallet 38 so that the pumping action will cease until the water isagain used from the trough.

The several parts of my device are compactly arranged and a singlewinding of the cable will suflice to operate the motor for aconsiderable period of time. Inasmuch as the power of the walking beamis transmitted to the pump rod approximately at the center of thewalking beam through the provision of the curved rack 28, the mechanismwill operate very smoothly and with practically no loss of power. Theuse of the segmental gear transmits the movement of the driving wheeland converts the rotary movement of the same into a reciprocatingmovement without loss of power and without causing any jarring of theoperating parts.

Having thus described the invention, what I claim as new, and desire tosecure by Letters Patent, is-
